Mal-1 is the debut album by the jazz pianist and composer Mal Waldron. It was released through Prestige Records in May 1957. It was recorded in November 1956.
A contemporaneous review by John S. Wilson stated that trumpeter Idrees Sulieman and alto saxophonist Gigi Gryce "play unusually well while Waldron contributes several provocative compositions and arrangements (especially a version of 'Yesterdays' that is a remarkably interesting rewriting of a real warhorse) and plays with typically dark, warm charm". The AllMusic review by Jim Todd stated, "Mal Waldron's recording debut as a leader presents the pianist with his many gifts already well developed".
